Nice, but i think you need more improvement to materials as colors doesn't match to the scene, the road is a bit smaller ( out of scale) with relation to the car. You may also adjust the angle of sun to 5 deg. up just on my opinion to give softer shadows.

Hello Jay,Thanks for comment. Yes the road is too small for the car. I'll try the sun. I think that I'll redo the all scene for it to be more appealing, with a house or some houses with some more cars and people. The purpose was to test Yafaray with a complex scene for exterior rendering. As I said it used 1.7 gig of memory, as I have 8 gigs I will push it more.
